Godson 2 is a family of 64-bit MIPS low-end performance desktop processors developed by the Institute of Computing Technology of the Chinese Academy of Sciences (ICT) in 2003. The Godson 2 processors are now developed by Loongson Technology (which was co-founded by ICT) and sold as low-power embedded and desktop processors. The Godson 2 is famous for being the first Chinese developed 64-bit microprocessors.
Overview
- Main article: GS464 µarch
The Godson 2 microprocessors are designed as a general purpose 64-bit that implements a MIPS64-like instruction set (Note that at the time ICT was not a MIPS licensee). Many improvements were done in Godson over its predecessor such as a wider pipeline capable of fetching and decoding four times as many instructions per cycle.
Initial Godson 2 models were fabricated on a 6-metal 0.18 µm process CMOS technology using automatic placing and routing. Later models enjoyed a series of process shrinks. The Godson 2 has integrated additional features over the years from just a CPU to an entire SoC incorporating a PCI/PCIX controller, memory controller, SPI/UART. Those processors utilized the a HyperTransport bus for the southbridge. Most recent models integrated much of the southbridge on-die as well including PCIe, SATA, and a USB controller as well as multimedia support (GPU, dual display, audio, and media decoders).
Godson 2 processors can be found in many low end laptops and embedded hardware manufactured by Lemote Technology.
